Abstract: Certain aspects of the present disclosure provide techniques for configuring timing advances for uplink communications resources. A method for wireless communications by a user equipment includes receiving, from a base station, signaling that configures a first timing advance and a second timing advance. The first timing advance is configured to be used by the user equipment when transmitting an uplink communication in a half-duplex resource, and the second timing advance is configured to be used by the user equipment when transmitting an uplink communication in a full-duplex resource. The method may further include transmitting, to the base station, a first uplink communication within a first resource using one of the first timing advance or the second timing advance based on whether the first resource comprises a half-duplex resource or a full duplex resource.

Abstract: Aspects presented herein may improve the performance and/or efficiency of a BFD procedure for a UE, where the UE may use DMRS to perform the BFD to reduce the occasion(s) of configuring multiple or frequent CSI-RS resources sets for the UE. In one aspect, an apparatus measures RSRP of one or more reference signals in a reference signal set for a BFD, the one or more reference signals include at least one DMRS. Then the apparatus compares the measurement for the at least one DMRS to a threshold. Then the apparatus initiates or restarts a BFD timer or a BFR procedure based at least in part on the measurement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a report that includes measurements associated with one or more downlink reference signals that are received using a set of candidate downlink beams. The UE may transmit one or more uplink reference signals using a set of candidate uplink beams. The UE may receive, from the base station, information that indicates, among the set of candidate downlink beams and the set of candidate uplink beams, a best uplink beam to use for one or more uplink transmissions. For example, the base station may select the best uplink beam based at least in part on the measurements associated with the one or more downlink reference signals and measurements associated with the one or more uplink reference signals. Numerous other aspects are provided.

Abstract: A network node may select a reference AM/PM impairment signature. The network node may transmit, to a UE, a first indication of the reference AM/PM impairment signature via a security signal. The network node may transmit, to the UE, at least one reference signal via a downlink channel. The at least one reference signal may include added AM/PM impairment based on the reference AM/PM impairment signature. The UE may receive, from a transmitter, at least one reference signal via a downlink channel. The UE may estimate an AM/PM impairment signature in the at least one reference signal. The UE may identify whether the estimated AM/PM impairment signature matches a reference AM/PM impairment signature. Further, the UE may maintain or discard at least one slot associated with the downlink channel based on whether the estimated AM/PM impairment signature matches the reference AM/PM impairment signature.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.
